The Art of Betrayal by Gordon Corera

I am still reading and enjoying this book about the secret history of MI6. I like spy novels, so I am pleased to find that the real world of spying is just as exciting as the fictional one. It's full of exciting escapes, safe houses, and strange and innovative ideas.

The terrible story of the long cover-up of Kim Philby and the betrayal of the agents sent into Albania was especially fascinating.
